LEAD AAC Encoder
The LEAD AAC Encoder Also known as compressor, this is a module or algorithm to compress data. Playing that data back requires a decompressor, or decoder. is a DirectShowÒ filter for compressing audio data using the AAC compression standard (ISO/IEC 13818-7). The AAC standard delivers high quality audio at lower bitrate compared to other audio encoding standards like ISO/MPEG Audio Layer-3; MP3.
This encoder offers both variable bitrate and constant bitrate. However, due to a limitation in the AVI multiplexer A module that combines audio and video into one file., the encoder offers constant bit rate only if it is connected to the AVI multiplexer.
